L = length of bimetallic strip (m)
dt = temperature difference (oC)
t = thickness of bimetallic strip (m)
A bi-metal strip with α = 14 x 10-6 K-1, length 50 mm and thickness 2 mm is heated 100 oC. The bending can be calculated as
s = (14 x 10-6 K-1) ((50 mm) 1/1000 m/mm)2 (100 oC) / ((2 mm) (1/1000 m/mm))
= 0.00175 m
= 1.75 mm
